Answer:
C.
Step-by-step explanation:
y = 1/ x must pass through the origin because when x = 0, y = 0.
So its either B or C.
A positive slope rises to the right ( 1/2 is positive), so its C.
You can also see that the slope of C is 1/2 because it passes through the points (0.0) and (2, 1).
If you visualize the problem, there are two concentric circles, the pool, and the pool plus the walkway. So, we have to subtract the area of these two concentric circles to find the walkway.
Bigger circle: Pool plus walkway
----------------------------------
diameter = 18 + 4(2) -- this is because there is 2 ft of walkway at each far end
diameter = 26 ft
Area = pi*(26/2)^2
Area = 530.93 ft2
Smaller circle:pool
---------------------
diameter = 18 ft
Area = pi*(8/2)^2
Area = 50.27 ft2
Area of walkway
----------------
A = 530.93 - 50.27
A = 480.66 ft2
Then the cost would be
Cost = $4.25 * 480.66
Cost = $2,042.81
Well, minusing 8 from every t just moved theh function to the right 8 units
it had no effect on the number of t intercepts (horizontal is t axis instaead of x axis)
originally, it has 1 t intercept at t=0
now it still has 1 t intercept, but now it is at t=8
22 miles,
30miles - 8 miles = 22 miles
Mikes trip to work is 22 miles farther than sam’s
Answer:
1: 152
2: 152
3: 152
4: 28
Step-by-step explanation:
1-3: They are all congruent. So if you look at the given angle, it is the same as 1-3.
4: This one is tricky. Since a straight line is 180, you have to subtract 180-152.
Hope this helps!
